Hertz Duct Silencers is a component of ventilation system used to\u00a0reduce noise\u00a0transmitted inside ventilation ductwork. Duct silencers are also referred to as\u00a0sound attenuators, sound traps or mufflers.\u00a0 They control, reduce, or limit airborne noise in ducts and openings in buildings, enclosures, or equipment rooms.<\/p>\n
